ShannonP

This function computes Shannon-Wiener Index for each cell of a matrix, 
using a parallelized approach and considering a specified moving window.

Provides methods to calculate diversity indices on numerical matrices
based on information theory, as described in Rocchini, Marcantonio and Ricotta (2017) <doi:10.1016/j.ecolind.2016.07.039>,
and Rocchini et al. (2021) <doi:10.1101/2021.01.23.427872>.

ShannonP function

<dl><dt>x</dt>
<dd>A numeric matrix representing the data on which the index is to abe calculated.</dd>
<dt>window</dt>
<dd>The width of the moving window to consider for each cell. 
The actual window size will be `(2 * window + 1) x (2 * window + 1)`. Default is 1.</dd>
<dt>na.tolerance</dt>
<dd>The tolerance level for missing data within the moving window. 
A window will be processed only if the proportion of non-missing data is above this threshold. 
Value should be between 0 and 1. Default is 1.</dd>
<dt>debugging</dt>
<dd>Boolean flag to enable or disable debugging messages. Default is FALSE.</dd>
<dt>np</dt>
<dd>Number of processes for parallel computation.</dd></dl>
